从创造到普及:吴晗先生的学术贡献

在新史学思想主导下,吴晗致力于一种社会的、民众的新明史研究,重新选择传统政治史的问题和研究路径,开创了以明史为中心、元明清一线贯通的研究模式。吴晗最具创造性的研究主要体现在明代政治、军事、社会史方面。他不仅在这些方面开拓出对于明史研究的展开有着重要意义的新课题,而且对这些新课题进行了具有深度的研究,得到了后来学者的广泛认同。20世纪50年代,吴晗由学者变为社会教育家,全身心投入到历史普及,形成了一套关于历史通俗化和历史普及的理论和方法,成为普及历史知识的积极倡导者,为史学和社会结合树立了良好的典范。     

古埃及护身符的制作原理、分类与文化蕴涵

护身符是古埃及宗教文化的重要艺术形式,也是古埃及人留下的文化遗产。护身符的制作遵循交感巫术原理。按照该原理可以把护身符分为3种形式:以"相似律"原理制作的护身符、以"感染率"原理制作的护身符、"相似律"与"感染律"兼有的护身符。护身符具有丰富的文化蕴涵,是古埃及人造就强势人格的法宝,也是古埃及人冥世观的集中反映,其中积淀着埃及文明的因子。护身符的运用,一方面为埃及珠宝工艺的发展带来契机,另一方面促进了埃及文明的传播。     

波里比阿论古典罗马共和国政制

本文重点探讨波里比阿的混合政体及其与罗马共和国政治生活实际的关系。首先讨论了波里比阿有关单纯政体产生、堕落和循环的理论,在此基础上,考察了他关于罗马共和政体乃混合政体、混合政体相对稳定的观念以及混合性质在罗马政体中的具体表现,并对波里比阿的理论与罗马共和国政治实际之间的关系进行了讨论,指出波里比阿理想化的论述与共和国的实际之间存在一定差距。本文指出,波里比阿已经意识到混合政体像单纯政体一样,注定会走向衰落,尽管速度相对缓慢。他有关斯奇庇奥美德的描述,正反衬了波里比阿时代罗马道德的普遍堕落。

Sputniks,explorers and propaganda: The discovery of the earth's radiation belts 1

Abstract

The most important scientific discovery of the early space era ‐ the 1958 discovery of the radiation belts of the Earth ‐ was made in the context of Cold War rivalry between the USSR and the USA. The paper uses previously unavailable archival records to reconstruct the relative contributions of American and Soviet researchers and their interations during the process of discovery. The former discovered what is now known as the inner radiation belt, while the latter observed the outer radiation belt and gradually came to realize the existence of two distinctively different zones of radiation. The uses of science for the purposes of Cold War political propaganda affected the behavior of scientists and led to the misrepresentation of the events in mass media.     

Oxygen isotopic composition of limpet shells from the Beagle Channel: implications for seasonal studies in shell middens of Tierra del Fuego

Shell middens distributed along the coastal areas of the Beagle Channel (Tierra del Fuego) testify the primary role of marine resources in the successful social dynamic of hunter–gatherer–fisher societies (HGF) in extreme high latitude environmental conditions. Intertidal and subtidal limpet species are frequently identified taxa of these archaeological deposits. We investigated whether shell δ¹⁸O of the limpet species Nacella deaurata is a valuable record of local sea surface temperature (SST) and ambient water δ¹⁸O (δ¹⁸Ow) fluctuations, and in turn can be used to estimate the season of its exploitation by Holocene HGF. Sequential shell δ¹⁸O of modern species track seasonal changes of SST and δ¹⁸Ow. The comparison of shell δ¹⁸O profiles of N. deaurata and Nacella magellanica (a coexisting species) suggests the occurrence of distinct growth rate and physiological adaptations between species. Shell δ¹⁸O of zooarchaeological specimens of N. deaurata from Lanashuaia II suggests that animals were exploited predominantly in winter and that experienced similar environmental conditions of present day at ∼1320 years BP. Results also indicate that N. deaurata is a valuable candidate for studying past seasonal changes in SST and δ¹⁸Ow in this southernmost part of South America.
